NEW YORK (AP) — She's not even a week old, but Blue Ivy Carter is already making music history.

Billboard says that thanks to her dad, Jay-Z, featuring her on his new song, "Glory," Blue becomes the youngest person to ever appear on its chart.

Jay-Z released the song about his first-born child with wife Beyonce on Monday, and it immediately became a viral sensation. The song, which credits B.I.C., features the sound of Blue's cries at the end.

The song's refrain is "The most amazing feeling I feel/Words can't describe what I'm feeling for real/ Maybe I paint the sky blue/My greatest creation was you. You. Glory."

State health officials on Wednesday dismissed complaints that patients in a hospital neonatal unit were mistreated while Beyonce was there giving birth to her and Jay-Z's daughter.

They had received two complaints about Manhattan's Lenox Hill Hospital, one made anonymously, the other from someone who had learned about the matter through the media, a health department spokesman said. Officials reviewed the complaints and dismissed them Wednesday night, spokesman Jeffrey Gordon said without elaborating.

Media reports said Beyonce and Jay-Z, whose real name is Shawn Carter, paid $1 million to take over a floor and their security guard blocked parents from the neonatal unit for hours. The hospital denied the reports, saying the couple paid the standard rate for an executive suite without disclosing what that is.

The hospital's executive director was heading up its own inquiry into the complaints, hospital spokeswoman Barbara Osborn said. The hospital was interviewing parents who had children in the newborn wing when Jay-Z and Beyonce were there, she said.

"We have spoken to seven out of the 10," she said. "None have reported being stopped from seeing their babies."

She confirmed that security cameras were briefly taped over when the Carter family was being moved, "but only when a security guard was present" on the fourth floor, where the neonatal unit is located. She declined to say why they were taped over.

She said that other parents at the unit did notice "enhanced security." But she said none felt restricted from accessing the unit or any other at the hospital.
